Plex cast network port

It seems that FAQ network port list is incomplete.
I opened all mentioned ports in the ubuntu firewall but still get 'No Players Found' from the plex cast menu. If I disable the ufw this feature is working fine and showing all players.
Did anyone figure out which port is used for that?

In the external firewall / router / modem, port forward only 32400 TCP to the static IP of your PMS server. There is no need for a second layer of firewall if the modem/router firewall is doing what it's supposed to do. That's why it's there and providing the NAT layer.

Dump all the Plex IPv6 unless you require it on the LAN. None of the Plex servers in the world respond to it.

Okay, I accept that answer
The router firewall is working fine, so there should not be any security issues as you said. Nevertheless it would be interesting to update the ports FAQ with multicast for those guys who need a firewall^^

When logs (server or client app) are requested for an investigation, please do NOT turn on "verbose" logging unless it is explicitly requested. Verbose logging makes things much more difficult in the majority of cases.
